In that case, I suggest, you will never set foot on an A380!!! All that you ask for was promised on the 747 (35 years ago) and none of it appeared/lasted.
Carriers could provide more space and bigger toilets today - but they do not.
Not sure about pitch, but width is certain.
Airbus 380 is 48 cm wider inside than Boeing 747, 78 cm wider than Boeing 777 and even more wider than DC-10 and MD-11.
The standard 555-seat layout of Airbus 380 has in Coach 3-4--3 configuration. 3-4-3 is also prevalent on Boeing 747, frequent on Boeing 777 and occasionally seen on MD-11... Therefore, a coach section of 3-4-3 Airbus 380 has 48 cm to divide between 10 seat columns and 2 aisles compared to Boeing 747. Thus, it must be more comfortable about width. Not sure about pitch and toilets.
Sure, the airline could alternatively insert an extra seat column, and fly Airbus 380 in 3-5-3 layout. It would still be more comfortable than 3-4-3 on Boeing 777 (unless you sit in the middle-middle seat).
But will they?
It was once asserted that no airline wants to seat 11 abreast on Airbus 380. Well, it was before the Kingfisher order. Emirates want to put in up to 644 seats in 2 classes. Kingfisher speaks of 750-800. Perhaps Kingfisher is going to have 3-5-3 seating. They would be the first.
Will the extra width last? Boeing 747 entered into service with 2-4-3 coach seating. Which is still seen, but rare - by now, 3-4-3 is standard.
What is the next Airbus 380 customer after Kingfisher?
